8. Check the backpressure to confirm that the regenerant path is ready:
a.
Note the pump pressure.
b. Disconnect the CES
REGEN IN
from the CD
OUT
(the high-pressure
side) and note the difference in the pump pressure.
c.
If the difference is less than 0.7 MPa (100 psi), the low-pressure flow
path is ready and you can proceed to the next step.
NOTE
If the pressure difference is greater than 0.7 MPa (100 psi),
refer to the ICS-5000+ operator’s manual for troubleshooting
information on high system backpressure.
4.1.6
Checking the Background Conductivity
If you are installing a CD, check the background conductivity before
continuing.
1. Set the pump
Purge
flow rate to 0.03 mL/min and the
Duration
to 900 s.
Click
Prime
.
2. Monitor the background conductivity. Verify that the conductivity is
<1
S before proceeding.
3. Remove the tubing assemblies between the injection valve
ELUENT OUT
and the CD
IN
.
4.1.7
Completing the Installation Qualification
Complete the Installation Qualification (IQ) and system function test to
confirm that the Dionex ICS-5000
+
system is correctly installed. For
instructions, refer to
Dionex ICS-5000
+
System Installation Qualification
(Document No. 065404), provided in the DC Ship Kit (P/N 072011, standard
DC; P/N 22171-62000, low-temperature DC).
NOTE
If you are installing an ED, fill and flush the liquid path (see
) and set up the eluent generator (see
) before completing the IQ and performing the
system function test. The test for an ED requires KOH eluent.
The test for a CD requires only deionized water.
